Plastic Air Diffusers & Vents

Stratus Plastic Air Diffusers & Plastic Vents

Plastic air vents offer a long-lasting, high-quality solution for any commercial HVAC system. Because these diverters are made from high-quality, high-impact plastic, they will not rust, change colors, or clog as easily as diverters made from metal. Stratus Plastic air diffusers by American Louver are lightweight and easy to install, and they make for a beautiful finish to any installation or repair.

At 1800ceiling.com, we carry a wide selection of plastic air diffusers, mounting frames, returns, and collars. We even have round and square plastic ceiling diffusers in a range of popular colors, including white, beige, and black. Shop our entire selection below to find the perfect match for your application.
